Aquatic Adventures – Northern Virginia Dive Center: Scuba Dive Computers offer both Safety & Convenience
For years all scuba divers used special Dive Tables to tell them how long they could stay down at any given depth, and how long they needed to wait prior to making another dive. The advantage of the Dive Tables is that they are inexpensive, fairly easy to use and most importantly they teach you the basics regarding diving depths and safety. However, today, most divers use Scuba Dive Computers to calculate these allowable dive times and to record their dives. In fact the Scuba Dive Computer is usually one of the first pieces of scuba dive equipment that most divers purchase.
All computers are similar in the way they work. They all include a program to determine how long you can stay down and depth gauge to determine what depth you are actually at. The Dive Computer is far more accurate then the dive tables since it knows what depth you are at any time throughout the dive.
What are the Differences in Scuba Dive Computers?
Air Only Dive Computers
There are several different types of Scuba Diving Computers from the simplest one button air only dive computer, like the Aeris XR-1 to the far more complex air integrated dive computers like the Aeris Diving Equipment T-3 or the Scuba Pro Diving Equipment Uwatec Luna. Just what are the differences between them? The simplest is the air only computer. It can only be calculate air dive tables so you do not get the extra bottom time that nitrox or enriched air tables might give you.
The One Button vs Two Button Dive Computer
One button dive computers like the Sherwood Diving Equipment Profile Computer are the least expensive. They are a little more difficult to navigate since one button controls both the function control and the control to move within that function. A two button computer like the Scuba Pro Diving Equipment Uwatec Aladin Computer is slightly more expensive but it is much easier to navigate since one button changes function and a second button moves within that function.
Air Integrated Dive Computers
Today many scuba divers like the convenience and ease of an air integrated dive computer like the Aeris Diving Equipment T-3 or the Scuba Pro Diving Equipment Uwatec Luna. These computers will not only monitor your no decompression dive time but they will also calculate exactly how much air you have in your scuba cylinder and what your remaining. This adds quite a bit of a safety factor since it almost eliminates any chance of running out of air while scuba diving. In fact Aeris Scuba Diving Equipment even has an air integrated computer that fits into your scuba mask called the “Compumask” offering hands free use.
Air Integrated Computers with a Hose or Hoseless
Air Integrated Computers can come either with a hose to connect to the scuba diving regulator or with a radio transmitter so that they are hoseless. The Air Integrated Dive Computers with a hose like the Sherwood Scuba Diving Equipment Wisdom or the Aeris Scuba Diving Equipment AI are both excellent computers and very easy to use. Aeris Scuba Diving Equipment also makes a hoseless model like the T-3 or the Scuba Pro Diving Equipment Uwatec Luna which is also hoseless. The ones with a hose are less expensive. The ones that utilize a radio transmitter have one less hose to deal with making things simpler.
Other Features – Digital Compass
There are many other features available in Scuba Diving Computers such as a Digital Compass. Zeagle Scuba Diving Equipment offers the N2ition 3 Dive Computer with a built in digital compass. The Scuba Pro Uwatec Luna also offers a built in digital compass in a hoseless air integrated model.
READ THE MANUAL
Regardless of which model an what features that you select it is very important that you read the owner’s manual. This is necessary for safety and to make sure that you are able to get the most out of your new piece of scuba diving equipment. Reading the Owner’s Manual will also help you prevent making common scuba equipment related mistakes. Last but not least – now get out and dive.
